Fixing Perl5 Core Bugs: Report for Months 35 & 36

Got out of the habit of fixing bugs for the last couple of months. Spent most of the time that I was able to devote to perl mainly doing other stuff; in particular, pumpkining the 5.14.4 security release, and trying to keep up-to-date with my p5p inbox, which seems to be a full-time job these days.

Hopefully I'll be able to put lots of effort into working on 5.18 blocker bugs for the rest of March.
